Littelfuse Non-Resettable Fuse 200mA, 125 V AC/DC, Super Fast Acting, 1.1Ω Resistance, 1206 Package 0466.200NR

Littelfuse 0466.200NR is a non-resettable fuse designed for protection circuits operating at 125 V AC or DC with a rated current of 200mA. It features a super fast acting (FF) fuse characteristic, ideal for protecting high value silicon integrated circuits, including alarm systems, audio/visual equipment, computer boards, power supplies, and medical apparatus.

The fuse utilizes an advanced high temperature substrate for its body and is manufactured with a compact 1206 case style. The terminal construction consists of tin over nickel over copper, delivering stable and reliable electrical connections. The fuse has a resistance of 1.1 ohms and a breaking capacity of 50 A, making it suitable for handling fault currents safely.

Its epoxy substrate body combined with copper, nickel, and tin-lead caps enhances durability even under thermal stress. The fuse operates reliably over a wide temperature range from -55°C minimum to 90°C maximum, conforming to strict CSA and RoHS approvals to meet international safety and environmental standards.

This surface mount technology fuse provides considerable space-saving benefits and is offered in reel packaging, facilitating efficient automated insertion during manufacturing. Its thin film design ensures compatibility with modern compact electronic assemblies.

Typical industrial applications include protection for alarm systems, audio and visual equipment, computer boards, portable telephones, power supplies, and medical instruments, especially where high-speed fuse interruption is critical to circuit integrity.
